With my original Apple Watch I didn't see any movements until the day before delivery, the only reason I knew it was coming was because of My Choice UPS. I got the Apple Shipping Confirmation the day of. I was charged on my credit card at the beginning of the week. I think this is what we are seeing again. My Thunderbolt 3 > 2 adapter will be here tomorrow via Fedex. We will see what else may show up in the next couple of days.
This is very common. They sometimes do not provide tracking until it ships from a US (or your countries) location. It is possible they will be overnighted, like iPhones, and shipping emails will not be received until early AM on the day they will be delivered.
